Objective: To explore the main active components and drug targets of Mongolian medicine Erdun-Wurile in the treatment of Parkinson’s disease and its potential action mechanism based on the network pharmacology, and study the binding ability of drugs and target proteins with molecular docking. Methods: The active components and corresponding targets of Eerdun-Wurile were mined based on the traditional Chinese medicine systems pharmacology database and analysis platform, TCMCSP). The mined data were screened under the term of pharmacokinetic parameters [oral bioavailability (OB)≥30%, drug-likeness property (DL)≥0.18]. GeneCards, OMIM and TTD databases of human gene-disease related databases were used to screen out the possible targets in active components of Eerdun-Wurile in the treatment of Parkinson’s disease. The Venn diagram was drawn by Cytoscape 3.9.1, and PPI network diagram was drawn with STRING database. The Bioinformatics and Metascape database were used to search the potential active ingredients of Erden-Wurile and potential targets for the treatment of Parkinson’s disease, and GO function analysis and KEGG enrichment analysis was performed on screened targets with molecular docking of small drug molecules and target proteins. Results: 118 kinds of active ingredients with good DL and oral absorption were screened from Eerdun-Wurile medicine, and 207 targets were predicted to treat Parkinson’s disease. GO function analysis and KEGG enrichment analysis showed that the mechanism of Mongolian medicine Eerdun-Wurile in treating Parkinson’s disease mainly involved with biological processes such as positive regulation of RNA polymerase II promoter transcription, positive regulation of DNA template transcription, positive regulation of gene expression. Pathways involved were AKT1, TP53, TNF, VEGFA, CASP3, etc. Conclusion: The effect of Mongolian medicine Eerdun-Wurile in treating Parkinson’s disease is the action result of multi-components, multi-targets and multi-channels, which provides theoretical basis for further research on treating Parkinson’s disease with Eerdun-Wurile.
